"We're anxious to get back onstage," Nick Jonas told Newsday Monday. "We've all gone and done things on our own -- which have been great and we're happy that we've had the time to do that -- but we're looking forward to being back onstage together."

That's why Nick, along with brothers Joe and Kevin Jonas, announced the unusual step of playing a concert before releasing (or even finishing) their new album. The Jonas Brothers will play Radio City Music Hall on Oct. 11, their sole American concert of the year. Tickets go on sale through Ticketmaster at 10 a.m. Friday. Fan club members can start buying tickets at 10 a.m. today through jonasbrothersfanclub.com.

The trio plan to work on their album during a short break between their other gigs. Kevin's reality show "Married to Jonas" debuted on E! Sunday night, while Joe's music competition show "The Next" debuted on The CW last week. And Nick says he's still waiting to find out if he'll become one of the judges on the next season of "American Idol."
